Hiding all the tiles in a layer

Lime
#1

Graham,

I’m using a tile layer to ‘draw’ some paths for my enemies to follow which I’ll refer to in code, i.e. check properties in the path tiles. I’m using a single opaque tile to do this in a separate tile layer.

The tiles show on my map when the map loads, why doesn’t this hide them?

 local enemyPath = map:getTileLayer("Enemypaths")  
 enemyPath:hide()

Also is this the best approach, i.e. will I still be able to check for the tiles and reference their properties if they are hidden?

Thanks four your help,

Cheers!

Rob

Your code does work as long as you create the visual first.

Here it is in action with a loop to show tile id’s for that tile layer (even though they are hidden)

  
display.setStatusBar( display.HiddenStatusBar )  
  
lime = require("lime")  
  
local map = lime.loadMap("Test.tmx")  
  
visual = lime.createVisual(map)  
  
local enemyPath = map:getTileLayer("Enemypaths")  
 enemyPath:hide()  
  
   
-- If layer exists  
if(enemyPath) then  
  
 -- Get the tiles   
 local tiles = enemyPath.tiles  
  
 -- Ensure tiles is not nil  
 if(tiles) then  
  
 -- Loop through tiles   
 for i=1, #tiles, 1 do  
  
 -- print gid  
 print("Tile:" .. i .. " id:" .. tiles[i].gid)  
  
 end  
 end  
end

Thanks evs for beating me to it. I was about to post that it should work fine but then saw your reply.

Thanks for your help. I’m afraid the following doesn’t work, this is my ‘constructor’ to build a map class:

  
function new(mapName)   
 local self = lime.loadMap("levelOneMap.tmx")   
 local visual = lime.createVisual(self)  
 local enemyPaths = self:getTileLayer("enemyPaths")  
 enemyPaths:hide()  
 print(enemyPaths.name)  
 return self  
end

There are no errors and the print statement prints the layer name but the tiles aren’t hidden in the simulator.

Could you email me your project so I could have a quick look at it? [import]uid: 5833 topic_id: 7904 reply_id: 28198[/import]
